Abstract

Bei einem mit einem Lüfter und einem Gas-Regelventil versehenen voll- oder teilvormischenden Gasbrenner wird im Flammenbereich ein Ionisationssignal mit Hilfe einer Ionisations-Elektrode gemessen. Ferner wird die Lüfterdrehzahl erfaßt. Aus dem Ionisationssignal und der Lüfterdrehzahl wird dann ein für die aktuelle Luftzahl repräsentatives Signal abgeleitet und dieses mit einem vorgegebenen Wert verglichen. In Abhängigkeit von diesem Vergleich wird ein Stellsignal für das Gas-Regelventil bestimmt. Um den Gasbrenner über einen langen Zeitraum sicher im optimalen Luftzahlbereich betreiben zu können, wird in regelmäßigen Zeitabständen oder in Abhängigkeit von spezifischen Ereignissen das Gas-Luft-Verhältnis des Gasbrenners überprüft. Dazu wird aus dem Ionisationssignal ein für die aktuelle Luftzahl und die aktuelle Leistung repräsentatives Signal abgeleitet und dieses mit einem vorgegebenen Wert verglichen. Aus diesem Vergleich lassen sich ohne besonderen Aufwand Informationen über den Betriebszustand des Gasbrenners ableiten.
